——定语从句（the Attributive Clause）
Name: ______________ Class: ______________ No.:______________
一、定义：
在复合句中,修饰主句中的某一名词或代词的句子（从句）叫定语从句.定语从句所修饰的词叫先行词.定语从句作定语放在先行词的后面.
引导定语从句的词叫关系词,关系词有：关系代词that,which,who(宾格whom, 所有格whose)和关系副词when,where,why.关系代词或关系副词放在先行词和定语从句之间,既起连接作用,同时又作定语从句的一个成分.如：
The girl who is standing on the stage is my sister.
正站在台上的那个女孩是我的妹妹.（关系代词who在句中作主语）
I can’t find the book (that) I bought yesterday.
我找不到我昨天买的那本书.（关系代词that在句中作宾语,可省去）
Madam Curie was a great scientist whose name is known all over the world.
居里夫人是一位全世界闻名的伟大科学家.
二、用法：
（一）关系代词的用法：
（1）that指物,有时也指人,在从句中作主语或宾语.作主语不可省略,作宾语可省略.

注意：
(一) which与that指物时可互相代替,但that比which更常见,尤其在口语中.但要注意that可用来指人,而which则不能指人.
只能用that不能用which引导的定语从句：

I want everything (that) I want.
⑥定语从句修饰的词中同时含有“人”和“物”的名词时,定语从句只能用that引导：

⑦定语从句修饰的词为one, ones时,定语从句用that引导：

⑧当主句的主语是疑问词 who或 which来提问时,为了避免重复,用that引导定语从句：]
Who is the girl that won the first place?
(二) who指人,that除指人外也指物,在从句中作主语或宾语.作宾语可省略,作主语不能省略.
